AURORA, ON -- (Marketwired) -- 07/19/13 -- Helix BioPharma Corp. (TSX: HBP) (FRANKFURT: HBP), a biopharmaceutical company developing drug candidates for the prevention and treatment of cancer, today announced that it has received conditional approval from the Toronto Stock Exchange to extend the expiry date of the 2010 Warrants (as defined below) by eighteen months, from August 5, 2013 at 5:00 p.m. (Toronto time) (the "Current Expiry Date") to February 5, 2015 at 5:00 p.m. (Toronto time) (the "Amended Expiry Date"). Helix also proposes to increase the exercise price for the 2010 Warrants from $3.40 to $4.15, effective from and after the Current Expiry Date (together with the extension of the expiry date, the "Proposed Amendments"). Helix does not propose to amend any other provision of the 2010 Warrants, and none of the 2010 Warrants is held directly or indirectly by an insider of Helix.

Helix intends to provide a letter to the holder of the 2010 warrants outlining the terms of the Proposed Amendments and Helix intends that the Proposed Amendments will only become effective in respect of those 2010 Warrants for which the holder signs and returns an acknowledgement, acceptance and request, which will be appended to such letter, to Helix on or prior to the Current Expiry Date, and that any 2010 Warrant in respect of which such acknowledgement, acceptance and request is not received by Helix by such time shall expire in accordance with its current terms on the Current Expiry Date.

The 2010 Warrants were issued as part of a private placement completed by Helix on August 6, 2010, pursuant to which Helix issued 4,530,000 units at a subscription price of $2.43 per unit. Each unit consisted of one common share and one common share purchase warrant (each a "2010 Warrant"), with each 2010 Warrant common entitling the holder to purchase, subject to adjustment, one common share at a price of $3.40 until the Current Expiry Date.

The Proposed Amendments will be effective on the Current Expiry Date, being more than 10 business days following the issuance of this press release as required by the Toronto Stock Exchange's Company Manual.
